RADIO SCKET AND TUBE.

Application :tiled October 12, 1927. Serial No. 225,771.

parent from the following description and d rawing.

in the drawing Figure 1 is an elevational view of the revised tube andthe especially designed socket in which it is fitted.

Figure 2 is a sectional view of the saine.

Figure 3 is a top plan view of the mounting or sociret per se.

Referring now to the drawing, by numerals, itwill be observed that thereference character l designates generally the improved mounting orsocket which includes the attaching base 5 of customary design, and an`upstanding socket 6. 1n the present instance this socket is formed atits top with an outstanding marginal flange 7 which functions as a stop.@n one side it is formed with a vertical. elongated notch 8 whichconstitutes `a guide. Y

Embedded or otherwise fastened to the base are conductor strips 9 havingtheir inner ends extending into the socket and terminatingin rigidconical projections 10 providing contacts. These are arranged as shownin Fig nrc 3 so that they are in proper circumferentially spacedrelation.

'lhe radio tubo is generally represented by the reference character ll,and the base 12 thereof is provided with a guide pin 13 receivable inthe notch 8. lin addition it is formed with screw threads 14.',lhe'threads l-l are adapted to be engaged with internal threads on acoupling collar 15 fitted on the socket G. Incidentally thiscollar isformed at its bottom with an inturned flange 15 which engages the flange7 on the socket. The depending terminals 16 are formed in their bottomswith conical recesses which fit down over the correspondingly shapedcontacts 10. It might also be mentioned that the aforesaid conductorstrips 9 are extended out beyond vone edge of the base to facilitate theconnection of Wires. In practice these will be marked so that the properwires can be readily connected therewith.

In inserting the tube in this structure it is simply placed straightdown lin a vertical direction, the pin 13 being placed in the guidenot-th 8. rl'hen the collar 15 is slippedup on the socket and ei'igagedwith the threads 14; in a rotary manner. This feeds the tube down sothat the conical recesses in the lowerr ends of the terminals orcontacts 15 telescopically receive the correspondingly shaped contactson the conductor strips 9. In this Way the contact of the tube and basecan be brought into firm engagement to overcome accidental displacementand to insure a goed electrical connection free from vibration andshifting.

The advantages of a structure of this kind will be quite clear topersons familiar with inventions of this class. Therefore, a morelengthy description is believed unnecessary.

Minor changes in shape, size, and rearrangement of details coming withinthe scope of the adjoined claims may be resorted to if desired. y

Having thus described the inventiom'what I claiinas new is zff 1. Aradio tubemounting. comprising a base having socket, rigidelectrical'contacts en said base located within the area of said socket,said socket being yprovided at itsupper end on one side with a guidenotch, a radio tube telescopically fitted into said socket and having apin movable-vertically down into said notch to aline and bringthecontacts on the tube into electrical connection with the con facts onthe base and coacting` n'ieans between the tube and socket 4tor holdingthe tribe in the socket, said coacting means comprisin a rotary screwthreaded collar connection between the socket and base port-ion of thetube.

Q. As a new product of manufacture, a radio tube mounting,comprising abase having an opstanding socket providedv at its top with a marginaloutstanding flange and formed on one side with a guide notch disposedvertically, conductor strips embedded in said base having their innerends extending into the socketand terniinating` in circnlnferentiallyspaced upstanding conical contacts, and a screw threaded coliar itted onsaid socket and having a flange engaging the fiange on the socket,together with a radio tube having a base portion tting in said socketand provided with screw thr ads connected with the screw threads on saidcollar, said base portion also having depending Contact pins provided intheir bottoms with conical recesses for relo ception of the aforesaidconical contacts.

in testimony whereof I a'ix niy signature.

ANTHONY J. KNILL.
